Which prefix means good, normal?

Which prefix means good, normal?

• A. Intra
• B. Epi
• C. Eu
• D. Exo

Answer: (B)

The key idea is a prefix that signals positive state or normalcy. eu- means good, well, true, or normal, and is used in medical terms to indicate a favorable or typical condition. For example, eupnea refers to normal breathing, euphoria to a feeling of well-being, and eukaryote to a cell with a true (nuclear) nucleus. The other options describe location or position—inside (intra-), on or upon (epi-), and outside (exo-)—and don’t convey quality or normalcy, so they aren’t the correct choice.
